Pummelo tree named &#39;5-1-99-5&#39;

ABSTRACT

A new red pummelo tree particularly distinguished by producing delicious and juicy red-fleshed fruit in central Florida, is disclosed.

LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED

Citrus grandis (L.) Osbeck

VARIETY DENOMINATION

‘5-1-99-5’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of pummelotree, botanically known as Citrus grandis, and hereinafter referred toby the name ‘5-1-99-5’. Cultivar ‘5-1-99-5’ is a red pummelo selectedfrom a group of open-pollinated seedlings obtained from the ‘HiradoBuntan Pink’ pummelo, currently the most popular variety in Florida.‘5-1-99-5’ was asexually propagated by standard inverted-T grafting tosour orange+Carrizo somatic hybrid rootstock and planted in Lake Alfred,Fla., where trees demonstrated all the characteristics of the originalplant.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new cultivar when grown under normalhorticultural practices in Florida. ‘5-1-99-5’ is a medium-large sizedpummelo with thinner rind than most favored pummelo selections.‘5-1-99-5’ features attractive dark red-fleshed segments that are moreuniform in size and shape than other pummelos. ‘5-1-99-5’ has adelicious flavor with just a hint of grapefruit bitterness. ‘5-1-99-5’fruit is quite juicy and fruit size is very uniform. Fruit on the treesometimes exist in clusters, and the rind can exhibit pink blushes wherefruit are touching.
